标准范围

ISO 12472:2002规定了一种试验方法，用于在木门组件中密封门框间隙的情况下，测定膨胀材料或系统的有效密封能力。该方法适用于评估暴露膨胀密封系统的功效，该系统与耐火性高达1小时的木质防火门一起使用。它不适用于比较隐蔽膨胀密封件。结果可应用于尺寸达到直接应用领域给定尺寸的经验证的单动单扇带锁木门组件。

ISO 12472:2002 specifies a test method for determining the effective sealing capability of intumescent materials or systems in the context of sealing door-to-frame clearances in timber door assemblies. The method is suitable for evaluating the efficacy of exposed intumescent sealing systems used in conjunction with timber fire resisting doors of up to 1 h fire resistance. It is not suitable for comparing concealed intumescent seals. The results can be applied to proven, single-acting, single-leaf, latched, timber door assemblies of sizes up to that given in the field of direct application.
